For waterfowl, mean monthly species richness was 1.5 ± 0.3 (mean ± SE, n = 11 surveys); mean monthly abundance was 86 ± 43, 191 ± 70, and 13 ± 16 birds in 1996-97, 1997-98, and 1998-99, respectively. Blue-winged Teal (Anas discors Linnaeus) were the most abundant duck (74%) followed by Mottled Ducks (Anas fulvigula Ridgway, 21%). Mean wading bird species richness was 8.48 ± 0.35 (n = 20 surveys). Cattle Egret (Bubulcus ibis Linnaeus) were the most abundant wading bird species during the wet season (64 ± 22% of individuals); White Ibis (Eudocimus albus Linnaeus) were most common during the dry season (39 ± 23%). Mean total wading bird abundance was greater during the wet than dry season (F 1,15 = 6.29; P = 0.02), with the increase driven by increases in Cattle Egret (F 1,15 = 5.46, P = 0.03) and large-prey visual foragers (F 1,15 = 5.47, P = 0.03). Compared to the 1950s, waterfowl species richness has declined 70% and abundance has declined 95%. For wading birds, mixed species breeding colonies no longer occur in the floodplain, and the community composition is dominated by the largely terrestrial foraging Cattle Egret during the wet season.

Occupancy rates for subregions of Washington ground squirrel sites typically exceeded 85%. However, the Seep Lakes Area in Grant County, the Hatton Area in Adams County, and the Foster Coulee Area in Douglas County each showed declines of ≥35% in occupancy rates from 2001-2003 to 2004. The Black Rock Coulee and Sagebrush Flats Areas in Grant County experienced 15% and 11% declines in active sites from 2001-2003 to 2004, respectively. Nine previously undocumented sites were discovered in 2004. Most (67.5%, n = 156) active Washington ground squirrel sites in 2004 were characterized by small estimates of burrow numbers (i.e., 1-50 burrows), with 17.7% (n = 41) of sites containing an estimated 51-100 burrows, 14.3% of sites (n = 33) having >100 burrows, and 0.4% (n = 1...
